ASIC weekly summary types and sub-types

Each week ASIC publishes summaries of what changed on its registers: companies registered, companies renamed, external administrations commenced, professional licences granted, directors disqualified and managed investment schemes registered. asicapi exposes these as purchased weekly summary extracts identified by readable type slugs, but every item still carries ASIC's own type and sub-type codes so you can tell a voluntary liquidation from a court winding up, or a new registration from a reinstatement. Weekly summaries are the most efficient way to monitor the register for new companies in a postcode or new insolvency appointments without polling individual companies.

Where it appears in the API

• type in the body of POST /v1/weekly-summaries is one of the slugs below, each mapping to a code in the weekly summary types table. The purchase returns a weekly summary extract with summaryType, weekStarting, items and postcodeTotals; GET /v1/weekly-summaries/{id} and GET /v1/weekly-summaries?type=&weekStarting= read the extracts you hold for free. See purchasing.
• weeklySummaryItem.subType on every item uses the weekly summary sub-types table.
• weekStarting (a Monday within the last 12 months) selects the week at purchase; the optional postcode query parameter filters the items when you read the extract.
• postcodeTotals[] on a new-registrations extract gives counts per postcode for the week.
• meta.product is weekly_summary on the purchase response. Buying the same type and week again returns the copy you already hold, without a fee, unless you pass "refresh": true.

API slugs, type codes and sub-types

ASIC's billing table also lists a report of changes to the charges register (code 930C). That summary has not been produced since security interests moved to the Personal Property Securities Register in 2012 and there is no corresponding slug.

Reading the external administration sub-types

The external-administrations summary is the one most often used for credit monitoring, and the sub-types map directly onto office holder roles.

Purchase a company extract for the company in the item and read GET /v1/companies/{id}/external-administration to see the appointee, the appointment date and the documents. The company's status will usually be EXAD after the appointment is processed; the summary can run a few days ahead of the status change.

Notes on the other summaries

• new-registrations includes deregistrations (DRGD) and reinstatements (REIN) as well as registrations, so filter on subType.code if you only want new companies. CHGT marks a company that changed type, for example from proprietary to public.
• name-changes gives the old name in company.name and the new name in newName. The ACN does not change.
• licences-granted covers professional registrations and licences. The LCFL sub-type for Australian financial services licences is the only modern licence type; the securities and futures sub-types reflect the pre-2002 regime and are rarely seen today.
• disqualified-directors items are people, so company is null and subject carries the name. Use the disqualified directors register for the period and grounds of the disqualification.
• An empty week is still a successful purchase: the extract has an empty items list (summary_empty), not an error. A week outside the 12-month window or not yet published returns summary_unavailable and nothing is bought.
